JOHN C. AUGUST RIECKE, OF BALTIMORE, MARYLAND, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE COMMERCIAL MANUFACTURING COM PANY, INCORPORATED, OF BALTIMORE, MARYLAND.

COIN-CONTROLLED PICTURE-EXHIBITOR.

SPECIFICATION forming part of Letters Patent No. 724,126, dated March 31, 1903.

Application filed April 12, 1902. Serial No. 102,537. (N model.)

To all whom it may concern:

Be it known that I, J our: 0. AUGUST RIEcKE, a citizen of the United States of America, re-

siding at Baltimore, in the State of Mary-' land, have invented certain new and useful Improvements in Coin-Controlled Picture Exhibitors, of which the followingis a specification.

This invention relates to new and useful :0 improvements in coin-controlled machines, and particularly to that class designed for use in picture-exhibiting apparatus.

The object of the invention is to provide novel means whereby a carrier containing I 5 views may be rotated slowly that each of the pictures arranged on the outer surface of the.

' In describing the invention in detail refer- 0 once will be had to the accompanying drawings,forming part of this specification, wherein like characters of reference denote corresponding parts in they several views, in which Figure 1 is a view of the interior of the casing, showing the invention in elevation. Fig. 2 is a fragmentary view of the motorreleasing means. Fig. 3 is a perspective view representing the sliding plate and the escapement. Fig. 4 is a view in elevation of the motor and connections. Fig. 5 is a perspective view of a camv connected with the motor. Fig. 6 is a similar view of the pawl which engages the toothed wheel and rotates the carrier. Fig. 7 is a perspective view of the guard and its operating-lever.

In the drawings, 1 denotes the casing having a window 2, and below the window is a slot (shown in dotted lines, Fig. 1) for the insertion of a coin. A chute 3 depends from 5: the slot and is so arranged as to convey and deposit the coin in a housing 4 on the end of a lever 5., A link 6 is secured to the inner end of the lever, and as the weight of the coin depresses the outer end the link is elevated. This link operates a lever a, carrying a releasing-arm o said arm being carried down and back until its angular extremity 7 passes from the blade of the fly-w-heel 8 and allows the motor to start.

A guard 9 is arranged at the outer end of the housing 4, and connected therewith is a lever 10, having an angular section which has a bearing in an aperture of the lever, so that it is free to swing, and the opposite end V of the lever terminates in close proximity to the periphery of the carrier, on which is arranged a trip-block 11, having an inclined 'face on which the end of the lever rides and by which the end of the lever is depressed. This depression results in the elevation of the opposite end of the lever, and consequently the guard of the housing, and as such is lifted the coin'is free to roll oi the lever into the coin-receptacle 12. The lever 5 isinclined downwardly by the weight of'the coin, and the adjustment is so exact as to allow the outer end of the lever to rise when the coin is removed. Hence as the outer end rises the inner end is depressed and the re- So leasing-arm 6 ascends until its angular extremity engages one of the blades of the flywheel and prevents further running of the motor. This operation is repeated each time a coin is inserted and the carrier has madea complete turn.

The mechanism'by which the power of the motor is communicated to the carrier consists of the following, viz: Secured on a spindle of the motor is a cam 13, so arranged as to ride on a pin lat of a lever 15. The cam is so mounted that it will be traveling on the pin and depressing the lever to keep the carrier in motion, the said cam acting in conjunction with a weight or its equivalent, as after the cam elevates the carrier-driving mechanism the weight causes its descent. On an upright 16 is a triangular plate I), having slots 17 and 1S. Guide-pins 19, attached to the upright, are so arranged as to allow the plate a vertically-sliding movement, since the guide-pins are inserted through said slot 17. Riding in the slot 18 is a stud 20 of the lever 21, and this lever has on its opposite end a pawl 22, which engages the teeth of the wheel 23, which wheel is keyed on the shaft 24, on which the carrier is also fixed. It will be seen that as the plate I) is elevated through the action of the cam the pawl 22 will be thrown into engagement with the tooth in ad vance of the one which it now engages, as shown in Fig. 1. \Vhen the cam has depressed the lever and elevated the plate to the maximum degree and then releases the lever, the weight causes the plate to descend. This action results in operating the lever 21 in the direction opposite to that heretofore described, and as the pawl of said lever is in engagement with the tooth in advance the wheel is turned the distance of one tooth, and this operation is repeated with each rotation of the cam. -3y this arrangement it will be seen that the carrier is turned the distance of one picture with each rotation of the cam. The cam-actnated lever is connected with the triangular plate-rod A. In order to prevent retrograde movement, I pivota dog 27 on an upright of the device in such a manner as to engage one of the teeth. On the triangular plate is arranged an escapement which rises and falls with the said plate. This escapement consists of a horizontal and vertical member 25 and 26, the former having a cut-away portion 27, through which the pins 28 in the carrier may pass. Normally one of" these pins abuts the vertical member of the escapement, and as the triangular plate is elevated the lower end of the vertical member 26 rises above the pin with which it was in contact, and when in this position the lug 29 of the horizontal memberis in contact with the next succeeding pin. As the lug 29 is in engagement with the pin at the time the vertical member releases the pin it engaged it follows that the carrier is held against movement until the plate starts down. In practice the triangular plate and the escapement descend and at the same time the carrier takes motion, and as the pin with which the lug was in contact describes an are said pin clears the edge of the lug and is free to pass through the cut-away portion of the horizontal member, and of course the pin with which the vertical member had been in contact had passed beyond the lower end of said vertical member before it descends.

reuse This operation is repeated each times new view is brought into alinement with the 0bservation-orifices. I

It will be understood that the number of views may be varied and that the stop mechanism-viz., the coin-ejector operated by the block on the carrier-may be arranged to suit the convenience of the manufacturer.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In apicture-exhibitor, a motor, apicturecarrier and a toothed wheel on a common shaft, a pawl in engagement with the toothed wheel, a lever which carries the pawl, means for preventing retrograde movement of the carrier, a sliding plate, connections whereby the plate is elevated by the motor, means for causing the descent of the plate, means whereby the lever is moved by the sliding plate, an escapement carried by the plate, said escapement comprising ahorizontal member with a cut-away portion and a vertical member, and pins on the carrier engaged by the escapement.

2. In a picture-exhibitor, a motor, a picturecarrier and a wheel on a common shaft, alever and means on the lever for causing a stepby-step rotation of the wheel, a sliding plate having connections to the motor,means whereby the plate moves the lever, an escapement comprising vertical portion and a cut-away horizontal portion, carried by the plate, and pins on the carrier alternately engaged and released by the escapement.

3. In a pict ure-exhibi tor, a motor, a picturecarrier and a wheel on a common shaft, a lever and means on the lever for causing a stepby-step rotation, a sliding plate having slots, a pin of the lever riding in one of the slots, means for reciprocating the plate and an escapement comprising a vertical member and a horizontal member with a cut-away portion, carried by the plate, and pins on the carrier engaged by the escapement.

4. In combination a motor, a cam rotated thereby, a lever operated by the cam, a pic ture-carrier and a wheel on a common shaft, a sliding plate operated by the lever, means whereby the sliding plate rotates the carrier, an escapement comprising a vertical portion and a horizontal cut-away portion, carried by the plate and pins on the carrier engaged by the escapement.

In testimony whereof I affix my signature, in the presence of two witnesses, this 22d day of March, 1902.

JOHN 0. AUGUST RIEOKE.
